The production process improve motor bearing performance measures

Bearing as a important choice of motor parts, if the production process can improve the performance of the bearing to use and can improve the use performance of the motor. In order to let everyone know something of the countermeasures to improve performance in the production of motor bearing, China bearing network to make the related introduction I hope to be of help. Motor bearing and motor or motor bearing, bearing is specially applied to the motor or motor on a special bearings. Motor used in bearing is a supporting shaft parts, it can guide the axis of rotation, can also turn over the shaft parts, under the concept of bearing is very broad. Improve motor bearing performance measures in the process of production, mainly has the following six points: 1, the motor assembly site to keep clean, bearings coated with grease, there is no dust float in the sky. And bearing with after the parts have to pass strict inspection before assembly, every tiny link should not be neglected. Shoulder of shaft and bearing fit, for example, if you are clear root fillet, operation, easy to produce stress concentration and the shaft twist off here; If the rounded corners is too large, or not in place when grinding, fitted with the amount of interference when bearing inner ring is super bad, or bearing can not reach the designated position, all these are the bane of bearing early failure. 2, dynamic balance quality are the crucial factors affecting the service life of bearing. The higher the motor, the greater the speed, and the higher requirements about the quality of the dynamic balancing. 3, related to the bearing parts - — Stand, end cover, rotor, bearing inner and outer cover of the coaxial degree is better, and to ensure in the running of motor don't damaged due to deformation of the parts. 4, related to the bearing parts machining accuracy to improve. Because of the high machining precision of the bearing itself, and bearings and related parts and components, a tiny amount of interference can cause the damage of the bearing. Practice verification, the use of nc machine tools with the size of the cutting tool machining bearing chamber can be control at zero tolerance zone. 02 mm range. 5, cooperate with bearing inner and outer ring of roughness also should improve as far as possible, otherwise, after a lot of dismantling the golden processing 'knife peak' wear off, the original design fit tolerance also changed. 6, grease in moderation, or bearing will fever. If the environment temperature is higher than 40 ℃, should choose high penetration of grease. On the other hand, should use penetration is low or the special grease. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
